Google Voice gives you 'One Number...for Life' -- a phone number that instead of being tied to a device or a location, is tied to you. Use GrandCentral to centralize your communication, customize your callers' experience, and make sure you never miss a call you want to take (or take a call you want to miss).

Strengths

• Option to screen calls

Weaknesses

• Students aren't use to this sort of phone service and sometimes hang up
